Replacement is easier than it looks, unless you have really big hands. The most challenging part is the little screw on the bracket underneath the intake. Unfortunately, it's an expensive part, but if it solves the problem, well worth the money. 
This evap system is complex and expensive. Lots of valves everywhere.
